CARRIAGE-STOP MECHAN ISM FOR TYPE-WRITERS.

Specification of Letters Patent. I Pgttgnfed Dial, 24, 1914.

Original application filed'February 7, 1901, Serial No. 46,379. Divided and this application filed November 15.1901, Serial No. 82,442, Renewed August 30, 1913. Serial No. 787,519.

To all whom it may concern:

Be it known tl t I, ENos S. Nn w uAN, a citizen of the United States, residing at Washington, inthe District of Columbia, have invented certain new and useful Improvement-s in Carria ge- Stop Mechanism for Type-lVriters; and I- do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap-pertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of'this specification.

This invention relates to typewriting machines and the object thereof is to provide therefor improved carriage stop mechanism, such stop mechanism being particularly adapted'for use. in connection with a combined typewriting and adding machine for which I have made application for Letters Patent of the United States by application- .filed on February 7, 1901, Serial No. 46379 (of which this application is. a division), although such stop mechanism is capable of use in a typewriting machine when used separately from said adding machine.

In the present and illustrated embodiment of my invention I have shown'and will hereinafter describe thesame in connection with the well known Burroughs adding ma-- chine, made in substantial accordance with Letters Patent of the United States Nos. 504,963, and 505,078 granted to William S. Burroughs on the 12th day of September,- 1893.

In the drawings Figure '1 represents a rear elevation partly" broken away of the adding and typewriting machine connected together for conjoint operation, part-s being broken away; Fig. 2 representsaside elevation as seen from the leftside of the two machines' operatively connected, and Fig. 3- repres'ents a-'view, on a larger scale than Fig. 2, showing in dotted lines the escapement rack lifted for tabulating.

Like numerals indicate the same parts wherever they appear in the several figures of thedrawing.

Referring to the drawings by numerals,

. changed to suit stance. located to the left of ,the. adding machine and close against the side 1 of the case thereof. Of the typewriting machine,

the top is indicated at 4 and the keys of the,

keyboardat 5, the keys 3 and 5 of'both machines being marked'with letters andcharacters such as 'will appear in the machine when set up for practical use. The carriage.

of the typewriting machine is arranged to travel laterally, in this instance behind both machines, for the reason that in the type of adding --machine illustrated the printing point is in the rear, but it will be readily understood by those familiar with the art that the position of the carriage may be.

the style of adding machine used. p Inasmuch as tlie'typewriter key elements and mechanism for making the typewriting impressions are concerned only in a general way with thestop mechanism which constitutes the present invention, it will suliice to state that eachof the keys 5 of the typewriter is operatively connected with a type bar 21 by a train of-mechanism coniprising an elbow lever 9 reciprocated bythe stem of such key, a rod 11, a movable reedbar 12, a link 14:, a multiplying lever 15, and

a rod 19 pivoted to such type bar. The type bar. are so arranged that all the type will strike the platen in the'horizontal line ,of

the printing. point of the adding machine and to-the leftthereof at a distance depending upon the position of the paper carriage.

27 indicates brackets projecting rearwardl y and upwardly from the back, of the machine and carrying a track 29 upon which is mounted, on ball-bearings 30, the our riage 31, the ballsbeing held in position by screws 32 (see Fig. 3), the track, and consequently the carriage, lying in a horizontal plane adjacent to the rear, or that face of the machine-in which the printing point is located. Upon the carriage 31 are brackets 33 which, by pivots 34, carry thcend plates 35, .in which the platen or roll 24 is journaled, and which support "other mechanism to be hereinafter mentioned. 1 l 36 indicates a rack in the rear of the car -riage,'the teeth ofwhichpoint downward, saidfrack resting on rollers 37- journaled in brackets '38, mounted on a rockin bar. or

shaft 39 parallelwith the rack an pivoted.

on its longitudinal axis in brackets- 40 'pro- 'jecting rearward and 'upward from the 7 track supports 27.- Upon the upper'face of the rack36 isja lug 4C1. 'The'brackets 40 are Qextendedfabove thejournals of the. rocking bar 39 and in their upper-ends carry a rigid- =-"stati0'naryhar 42 (which I -denomin'at'e' the rf tabulating'rail.) provided on its front and I rear edges with graduated notches 43 to reeeive an adjustable stop or pawl 44: which,

I when thelrack 36 is in itsupper-position, will engage the lug 41 and stop the travel --of the rack atany predetermined point to j which the stop-A41 has been adjusted.'- The rack 36 is. mounted in the ends of bars 45 swinging from the pivots 34L "and. its normal position is suclifas to permit the lug 4 1 topass. under stop 44; but t9 raise it up so that the stop willbein the pathofthe'lug, the

rock-bar39. is provided with a pendant lever-arm 46 connected by rod 4'} with a lever ;.48pivoted at 4:9 to the inside ofthe front 'of'the case of the maehi e and'provided v with a push key or bar 50 at itsupper end projecting through the front of the machine. Whenthe bar or'key- 50, is pushed inward the lever arm 4 is pulled forward, the rockfbar turned and the rack thrown up to bring the lug 41 in the path of thestop 4:4. This, mechanism is bests'hown in Fig.2 and is only intended for'useto permit the operator to quickly shift the, carriageto a "predetermined point, the usual longitudinal feed ofthe carriage to the left being-accom- 'phshed by means ofa spring (not shownl in a drum 51 connected'to the carriage by a '45-. cord 52,v such feed taking place when the rack is in. its lower ornormaljpositionand "bein'ggoverned by an escapemenathe teeth 4 53 of which alternately engage each successive'toothof-the rack. 7 In .the present instance the bar 36 consists of: two parts, thelnpper one of which hasan overhangingor rearwardly extending flangepwhile'jthe lower part consists of the notched bar'proper with which the escape= 55 'me'nt mechanis n-directly cohperates, it being understood thatthe stop 41 is formed orarranged on the upper part'of the bar 36 in any suitable manner. w-hich is-arr'angedto oscillate in the manner hereinbefore described, cooperates with said flanged portion of the, bar by pressing against the lower side or surface of such flange when the operating arm 46 is drawn- -forward to the dotted-line, position shown 5 in Fig. 3. jA'pivotedlever 122 is also pro-j connections including the reciprocating. rod

104, and as an incident of the regular add- The roller 37 i vided, forraising the feed rack 36 off the escapement tooth, 1

The escapement is operated in the well known manner to feed therack one step after each impression of a type,;thcj movement forward of the reed-bar 12 carrying with itthe transverse bar 545" at the upper end of the vertical arm of an elbow lever 54, which" elbow lever, through intermediate.

59, serves to oscillate the lever 60, mounted on the bar 61 pivoted between brackets 64 projecting from the track frame, and throws rearward the arm 62 which carries the teeth of the escapement, thus moving so i the teeth alternately in and out of engagement with the teethof the rack and permitting the rack to be moved one space to the left as ordinarily done in typewriting machines. The space key 79 of the typewriter is also operatively connecte'dwith the rod 59 to operate the escapement mechanism in the same manner. The escapement arm 62 is' provided at its upper end with a pivoted tooth 62, held uprightby a'spring 62 in order that such tooth may yield and slip over, the teeth of the rack when moved to the left, butwill rigidly engage and move the rack when moved forward.

It will be understood that in the combined ,typewriting and adding machine in which my invention is embodied, one carriage and platen suflices for both parts of the machine, the regular adding machine carriage being dispensed'with; The platen of the carriage is provided with mechanism not directlyinvolved in the present invention for turning it to cause a linespacing feed of the paper, both manually through a lever be'qiii'ckly shifted longitudinally to any desiredfcolumnar position upon the adding ma-s 12o chine which may be selected, it being understood that-the operation of the push button 50'at the front of the machine and the consequent oscillation of'the roller 37 and bar 36 causes disengagement between the escape ment inechanism and such bar 36, and per mits the carriage to advance to the columnar position whlch 1s predetermined by the position of the adjustable stop li on the bar 42. Any desired'figures being then deated, but the paper is automatically fed one line upward at the conclusion of the printing operation, as before stated.

While my invention is embodied in a com-- bined adding and typewriting machine, it is obvious that the stop mechanism above described maybe employed to position the carriage in a simple typewriting machine; also that it may be adapted to other combined mechanisms. may difi'erfrom those above detypewriting and adding machines inwhich the printing points of the two machines face the, platen in the same direction and in timement, although the adding and typewrlting scribed, by suitable modification of the connecting'and cooperating mechamsm .herein shown and described.
